HINGE.

Specification of Letters Patent.

Application filed; February 27, 1912. Serial No. 680,330.

which may be used in either right or left position and in which the pin, while loose and removable in some positions of the leaves of the hinge, will be held securely in all other positions of the leaves.

In the accompanying drawings which show the preferred forms of my invention: Figure 1 is a perspective view of the assembled butt or hinge. Fig. 2 shows a plan of the butt as attached. Fig. 3 is an enlarged end view with the outer portions of the leaves broken away. Fig. 4 is a side viewof a section on the line 4-4 of Fig. 3. Fig. 5 is a view in perspective of the separated leaves and the pin partially extracted. Fig. 6 is a view similar to Fig. 5 but showing a modified construction.

For convenience of description the two leaves of the hinge as shown in the drawings will be referred to as right and left leaves respectively, but it will be readily understood that when used in the reversed position' the terms right and left are interchanged.

The hinge comprises the two leaf members 1 and 2 of wrought iron, mild steel or other metal, each member being provided with spaced eyes or knuckles 3 and 4 formed in the usual manner from straps cut in the leaf blank. As shown, the left hand leaf member has three knuckles spaced apart to receive between them the two knuckles 4 of the right hand member 2. When assembling the knuckles are brought into allnement and a metal pin 5 is inserted.

So far the construction of the butt or hinge is common and is known as the ordinary loose pin butt or hinge. This form of hinge was found objectionable, however, as

the pin could be readily driven out or removed and the door or window blindcould be easily opened, and the objectof my inventlon is to provide a construction wherebythe pin will be securely locked in all posit-ions of the hinge except that particular onein which the pin may be readily removed. To this end the pin 5 is provided with a lug or projection 6 which may be formed integral with the pin -or may be made by driving a piece of metal into a recess formed in the pin. This lug or projection 6 is located on the pin-in position to fit in a recess or seat 7 formed in the outerend of the top knuckle 4 of the right leaf 2,

and the end knuckle 3 of the left leaf is proided with a groove 8 cut in its inner wall hich permits the passage of the lug, and when assembled with the lug 6 received into the seat 7 the pin is securely held, as the inner end of the knuckle 3 closes the open end of the seat 7 Preferably the seat 7 and the groove 8 are located in their respective knuckles so that they are only in alinement when thet-wo leaves are in a position at a right angle to each other.

Instead of grooving'the end knuckle as shown in Figs. 1 to 5, the passage for the lug may be formed by cutting the strap for the end knuckle slightly short, so that the strap when bent to form the knuckle will not entirely close and a slot or passage 8 as shown in Fig. 6 will be left between the end of the strap and the leaf.-

If desired the head of the pin may have marked thereon an arrow or other indicator to indicate the position of the lug so that in order to remove the pin it is only necessary to bring the slot or groove in the knuckle in alinement with the indicator. When the groove is formed wholly interiorly of the knuckle, as in Fig. 5, an indicatormark may be also made on the exterior of the knuckle to show the position of the groove.

The recess or seat 7 in the knuckle 4 may be a notch or a slot or passage cut through the entire vertical length of the knuckle, the object being to provide any suitable aperture into which the lug or project-ion 6 will fit. Should it be deemed desirable to use waslv ers of metal, fiber or any material between seat to receive said 111g and hold the pin the respective knuckles, these Washers may from turning While the other knuckle is arbe out to allow the passage of the lug 6. ranged to permit the' passage therethrough Having thus described my invention I of said lug. 5 claim: In testimony whereof I afiix my signature 15 A loose pin butt or hinge comprising a in presence of two witnesses. plurality of leaves each leaf having a EDWIN J.
